This bag is rather beautifully made, but it really is VERY large. My 18.2 "swim in it. The advantage is that you can put all the accessories you want and even a A4 workbook without problem. The separation is not very practical, high quality because you can not put that a difficult position to properly rig a computer 18 ". The computer of the support strap is not long enough to scratch, this is nerd! It is not expensive so overall 3 *.
